- receiving end 35 arranged in the air chest 7 and its discharge end 36 in the cylinder section 16. The pipe 3lextendsdownwardly' g to a point near the"bottom of. the water chamber 1 where iffis' provided with a horizontal run 37. Themes 25, 29, 33 and 37 bracket and spring support 41 within the bcttom of the water chamber. The levers b the point 47-.

and a are likewise supported in a certain position by means of a spring 42 surrounding a plunger stem working in a guide 43- at the'upper end of the water chamber 1. Each plunger stem has a head 44 against which the .float 38 is adapted to strike as it reaches the upper or lower limit of its movement, said plunger in turn operating against the adjacent levers to open the valve-0 and close the valve 6 of the upper set and. to open the valve'cl and close the valve a of the lower set, the levers controlling said valves being fulcrumed as shown to produce the operation described.

The suction pipe 24 is provided with a branch 45 which leads into the suction port 10 above referred to and from the pressure port ll'of the master valve a combined pressure and suction pipe 46 leads into the upper part of the water chamber 1, terminating at From the connection withjthe accompanying drawings the operation of the water elevator will now be understood. When the water chamber 1 isfilled, the valves 0 and b are" tripped by means ofthe float 38 so as to force the piston 13 downwai dly and carry the master valve 8 to the position shown in Fig. 2. This opens the pressure port 11 and com'pressedair is .forced through the pipe 46 into the top "of the water chamber, pressing the water outwardly through the discharge pipe 4:...VVhen the water chamber 1' is nearly empty, the heat 38 trips the valves a and d allowing the compressed air to pass into the lower cylinder section 16, the piston 13 being foifegoing description taken in thereupon shifted upwardly so asto cause the valve 8 to bridge the ports 10 and 11. This produces a suction ,in the-water chamber lthrough thepipe 46,-.--,thereby opening the foot valve Bji'a'n'd permitting the water to enter and re fillthe chamber 1. This operation continues indefinitely as long as there is a supply of water and as long as the air compressor is in operation, the float serving to' trip the small controlling valves by means of which the master valve is operated in the manner and for the purpose above stated. In case of the water supply running short, no air will be wasted as the automatic part ofthe mechanism will be thrown out of operation.- If there is an ample supply of water, then the elevator will operate under full head pressure on one end of the valve piston-and partial vacuum or suction pressure on the other end to throw the valve in workin position;

What I claim is v 1. In a water elevator, a submerged water receiving and delivery chamber, fa water inlet check valve for said chamber, an air compressor, air pressure-and suction pipes'connected with said. air compressor, a slide 'w valve controlling said pipes, a reciprocatory piston for actuating said valve, a cylinder in which said piston works and having its opposite ends in communication with said pipes, a float 1n said water chamber, and

float operated valves controlling said pipes I and arranged at the top and bottom of said water chamber.

2; In a water elevator, a submerged water receiving and deliverychamber, a water inlet check valve for said chamber, an. air compressor, air pressure and suction pipes connected with said air compressor, a master valve controlling said pipes, a cylinder and piston for operating said master valve and having said pipes in communication therewith, a float in said water chamber, and float operated valves controlling said pipes and arranged within and adjacent to the top and bottom of said water chamber.

In testimony whereof I ailix my signature in presence of two witnesses.
